"Automated tests" are simulations of user actions on your website. For example, clicking a button, filling out a form, searching for a product, and so on. With automated tests, we can simulate almost any user action, which means we can guide a "virtual user" through the entire journey of your website and lead them to make a purchase, ensuring that the purchase is completed. If an error occurs at any point (for example, if the "virtual user" cannot fill in a form field or click a button), the automated test will immediately notify you of the error.
